SPECIFICATION forming part of Letters Patent No. 518,147, dated April10, 1894.

Application tiled January 25,1893. Serial No. 459,645. (No model.)

To a/ZZ whom t may concern:

Be it known that I, JOSEPH M. HURLEY, a citizen of the United States,residing in Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Molds for CastingRadiator- Sections, of which the following is a specification.

My invention relates to certain improvements in making molds for`casting radiator sections,whereby the core can be more cheaply made andmore truly and quickly laid in place in the mold, thus insuring aperfectly true casting of even thickness throughout, all of which willbe fully and clearly hereinafter described and claimed, reference beinghad to the accompanying drawings, in which- Fgure l is a cross sectionthrough the core lying in the lower half of the core box. Fig. 2 is atransverse section through a liask, cutting through the mold and core inor about line a a, Fig. 3. Fig. 3, is a top view of a flask for moldinga radiator section, showing the under portion of the mold and the coreset in place therein. Fig. l represents a longitudinal central sectionthrough a flask for showing the inside construction of the same.

The flask-1 and la, is made in the usual manner with the exception thatcach half, l and l, is provided on each inner side, (where the two partscome together) with an inwardlyy projecting flange, the lower flange, 2,having a series of semicircular concave g-uiding depressions, 3, and theupper ange a corresponding `series of depressions 3thereb'y forming aseries of holes in which the anchors or supporting wires 7, on the corearesecurely held in place when the flask is put together.

In Fig. l, I have shown the mold, 4, in which the core is made.V Thiscore is made of the usual material and in two pieces 5 and 5, in theordinary way.

The core box (or mold) may be made of wood, of cast iron which ispreferable, it is also provided With a similar series of semicirculardepressions, 6, made the same size every way and the. same distanceapart as the depressions, 3, in the flask so they exactly coincide ineach.

In making the core, the first half, 5, is made and a series ofsupporting wires or anchors, 7, are put onto the upper side of the coreso as to fit down into the depressions, 6, in the core box, (enough ofthese anchors being used to properly support the core,) they are allmade of the same length ,and are set so as to touch the outer end of thedepressions in which they are fitted so asto project along in the sandcore up to the vent hole, 8. When the other half 5, of the core is puton and the whole dried and cemented together in the well known way thepins or anchors, 7, are rmly held into the core. Thecore isnow in acondition to be set in.y the mold preparatory to casting a radiatorsection, this is easily and quickly done as the anchors 7, being all ofthe proper length-.they t exactly in semicircular depressions 3zand 3a,in the Iiask, which when the Iiask is put together forni a series of.holes in which the anchors are held securely.

From the above description it will be seen' that the core can be almostinstantly put in place and laid exactly true, and that no mistake can bemade as almost any one of ordinary intelligence can set a core exactlytrue so that a casting made therefrom will be of even thicknessthroughout. -It will be further seen that the core thus set-and theflask put together, will be securely and rigidly held in its exactposition.

I claim as my invention- A mold for casting radiator sections,consisting of a flask in two parts l and l, each part having an inwardlyprojecting flange provided with a series of semicircular depressions 3and 3, extending part way across the face of the flange, asand moldandacore having a series of anchor pins extending 011tward and adaptedto fit in the depressions 3 and 3f, substantially as described.
